You can take the blue finish off of a gun, and if you polish the gun (properly, mind you), you can probably get a smooth, shiny finish that almost looks like stainless.
However, the environmental protection that the blue finish gives you will be gone, and your gun will be subject to rusting very quickly, unless you keep it well oiled all over. Not the best thing for a gun that you intend to use.
